EMC in product development (part 5)

Detail EMC design . This article is a part of a series of texts that will deal with the EMC challenge in terms of project management and the practical EMC activities at different stages in the project flow.
Different companies all have their own way of describing their project flow, so to keep it simple we will use the labels as given in Figure 1. We can call it a generic project flow. The picture only describes the basic outline of the work packages. These articles will describe the actual practical work we want to do in the project to “make EMC work” in a time- and cost-efficient way. Each part of our series will fill in the details for each part piece by piece.
This is the 5th part – Detail EMC design – in our process picture.

EMC Challenges and Solar Panel Systems

The use of . solar panel systems is rapidly increasing and some of these systems are co-located in the vicinity of wireless systems. Measurements have shown that the radiated emission from solar panel electronics can reach considerable levels, in some cases even above CISPR 22 Class B. Here, examples of interference impact is discussed for two examples of wireless applications, air traffic control communications (ATCC) and High-Frequency (HF) communications. The overall conclusion is that co-location of solar panel systems with wireless communications, must be carefully analyzed not to create interference problems.

Why electricity kills bearings – new insights

An article in Electronic Environment . 2017/2, is about the fundamental failure mechanisms (capacitive, inductive coupling and frame voltage) that cause EDM (Electric Discharge Machining aka Bearing Currents or Electric Erosion) in bearings. This article expands on the theme and shows why “The Simple Explanation”, The Mathematical Models and the Real World view on EDM differ, both in nature and in practical use. It also adds a couple of new insights that are becoming more and more valid with the widespread use of Frequency Inverters and loads with higher-than-normal capacitance to ground.

Massive IoT and EMC

Abstract — . The technical development towards the full vision of the Internet of Things (ioT) is expected to reach it´s full potential by the coming 5G wireless technologies. This will open up for so called massive IoT characterized by co-location densities in the order of 200000 devices per km2. This development will affect the area of Electromagnetic Compatibility (EMC) in a number of ways and may even be the most challenging issue for the EMC area since it was born for over 100 years ago. In this paper, some of these new challenges are highlighted and discussed. Furthermore, numerical results from some dense co-location scenarios are presented to show examples of interference challenges to be handled.

Troubleshooting EMI (Part II, Susceptibility Problems)

Some simple hints . for identifying and fixing EMI troubles. This second part of our EMI Troubleshooting guidelines is devoted to investigation and cure of EMI susceptibility problems. Since, according to our former article (Ref.1) conducted tests are faster and easier to perform, we will concentrate on these and avoid more complex and expensive radiated susceptibility test set-ups. The first half of this article will address the situation where the equipment at stake is still in the plant or lab, at the end of its development phase or in an early stage of production. The second half will cover the more difficult cases where the faultly equipment is already in service, installed at some customer site.
